So it is rather awkward that the far-right group's deputy leader is of foreign descent, according to an amateur family history researcher.

A blog written for the Exposing Britain First group states: "I’ve been studying family history now for long enough to suspect that you aren’t completely British. Fransen is not a British name. So I decided to have a little dig around.

Fransen was recently re-elected to deputy leader

"Let’s start with your paternal grandparents; John Joseph Fransen, or rather Jan Jozef Wynand Fransen. Born in the Netherlands in 1927, Jan came to England with the Dutch Naval fleet."

The writer also examines the maternal side of Fransen's family and comes to the conclusion it's highly likely they were Jewish.

The blog then goes on to outline the irony of Fransen heading such an anti-immigration group when so many of her close relatives were reportedly immigrants themselves.

Other policies the group support include:

– Make it an act of treason to implement any policy or measure, or sign any agreement, that facilitates and / or results in significant numbers of foreigners entering the sovereign territory of the United Kingdom with the aim of settling.

- Completely halt any further immigration except in special cases such as genuine marriages where strict citizenship criteria has been met.
